My dad loves fishin, and lately he’s been getting into squid fishing.Last weekend he got quite a big one, 70 cm!That’s not so cool on its own, but calamari skin is. I know they can change their skin “color”, but I had no idea they could do it even after dead!

You can apply “Core Animation” to any view (that is, custom NSViews, OpenGL Views, WebKit Views, NSProgressBar, anything!) That Means you can “pos-filter” any view with the well-known CoreImage Filters!
